LynnR,
I just read in Dr. Hulda Clark's book, "A Cure for All Cancers" that she tested most vitamin C supplements as containing 'Thulium" -- a toxic element. Some of us can detox it- but your daughter's liver may be over-taxed and not be able to detox it as quickly.

Thulium isnt good for any of us. The only reason it is in most Vitamin C supplements is because of processing. It isnt naturally in Vitamin C.

Dr. Hulda found that Bronson's vitamin C supplements tested okay.

In any case, try to get her to eat the most natural form of Vitamin C as possible-- probably fresh organic fruit high in Vitamin C daily.
Maybe in her case- you may have to.
